13. X-ray tube output is increased most strongly by increasing the:

a. Voltage across the tube

b. Atomic number

c. Anode diameter

d. size of the tube

7. For an absorbing medium with thickness t the quantity exp (-ut) is independent of:

a.  Incident photon intensity

b. Photon energy

c. Absorbing medium atomic number

d. mass attenuation coefficient

Explanation / Answer

Question 13) answer) option a) Voltage across the tube

Reason : increment in the anode's current and atomic number (Z) increases the output , but the largest increase is seen when we increase the voltage across the tube , as the output coming is the square of the voltage ( kVp)
